[FIXED] Custom JRE with JavaFX 11

Issue

I'm Using JDK11 and JavaFX11.

I created a custom JRE for my sample FX module program using Jlink, but when I try to run with the custom JRE, it renders errors as below:

This is how I created my custom JRE (no errors):

jlink --module-path ..\jmods;%PATH_TO_FX% --add-modules java.base,java.desktop,jdk.unsupported,javafx.graphics --output FXJRE

This is how I tried to run (with errors):

FXJRE\bin\java --module-path %PATH_TO_FX%;mods -m com.javafxdemo/com.javafxdemo.JavaFXDemo

The error messages:

Graphics Device initialization failed for :  d3d, sw

Here is how I compiled:

The source JavaFXDemo.java:

package com.javafxdemo;

import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.stage.Stage;

public class JavaFXDemo extends Application {
    @Override
    public void start(Stage stage) {
        stage.setTitle("Hello World");
        Group root = new Group();
        Scene scene = new Scene(root, 300, 250);
        Button btn = new Button();
        btn.setLayoutX(100);
        btn.setLayoutY(80);
        btn.setText("Hello World");
        btn.setOnAction(actionEvent -> System.out.println("Hello World"));
        root.getChildren().add(btn);
        stage.setScene(scene);
        stage.show();
    }
    
    public static void main(String[] args) {
        launch(args);
    }
}

module-info.java:

module com.javafxdemo {
    requires javafx.base;
    requires javafx.graphics;
    requires javafx.controls;
    
    exports com.javafxdemo;
}

This is how I compiled.

javac -d mods\com.javafxdemo --module-path %PATH_TO_FX% src\com.javafxdemo\module-info.java src\com.javafxdemo\com\javafxdemo\JavaFXDemo.java

After compilation, I have module class files as below:

├───mods
│   └───com.javafxdemo
│       │   module-info.class
│       │
│       └───com
│           └───javafxdemo
│                   JavaFXDemo.class
│
└───src
    └───com.javafxdemo
        │   module-info.java
        │
        └───com
            └───javafxdemo
                    JavaFXDemo.java

I can successfully run as below:

java --module-path %PATH_TO_FX%;mods -m com.javafxdemo/com.javafxdemo.JavaFXDemo

I can run with the default JDK11 though.

How can I successfully create a custom JRE and run the sample FX module program with it?

Solution

If you go to this link, you will notice there are two flavors for the JavaFX distribution for each platform:

The JavaFX SDK is the one you are using as:

export PATH_TO_FX=/path/to/javafx-sdk-11/lib

and if you check the files under lib, these are jars.

The JavaFX jmods on the other side contains the jmod format.

And if you read about the jmod format here:

For most development tasks, including deploying modules on the module path or publishing them to a Maven repository, continue to package modules in modular JAR files. The jmod tool is intended for modules that have native libraries or other configuration files or for modules that you intend to link, with the jlink tool, to a runtime image.

In other words, if you use javac or java to run your jar or module you can use the SDK, but if you are using jlink to create a custom JRE, you need the jmod version.

Once you have downloaded the jmods, unzip them and create this variable:

export PATH_TO_FX_JMOD=/path/to/javafx-jmods-11/

Now you can create the JRE:

jlink --module-path %PATH_TO_FX_JMOD%;mods --add-modules=com.javafxdemo --output FXJRE

and run:

FXJRE/bin/java -m com.javafxdemo/com.javafxdemo.JavaFXDemo
